Sometimes it is necessary to limit the size occupied by the files of image archives to prevent that they take too much disk space. The size of JPEG image files can be reduced by using a lower quality factor when saving to a file but it is not easy to determine what is the smallest quality factor reduction that guarantees that an image file will not exceed a given limit. This class provides an approximate solution based on a few tests using different quality factors and then using interpolation to reach a reduction factor close to the ideal value that can be used to keep the file size near the limit.
